Abstract: We introduce a notion of what it means for one graph to be a good spectral approximation of another, and prove that every graph can be well-approximated by a graph … Dan has won a ton of fancy prizes and there are so many people in the audience to watch him. In mathematics, spectral graph theory is the study of the properties of a graph in relationship to the characteristic polynomial, eigenvalues, and eigenvectors of matrices associated with the graph, such as its adjacency matrix or Laplacian matrix.

Spectral graph theory has powerful concepts which can be adapted to sheaves, and the more we know about the spectral theory of sheaves, the better equipped we will be to approach new problems. Spectral graph theory. We can arrive at an equivalent de nition of weighted directed graphs using only a vertex set V and a weight It turns out that Ramanujan expanders are the best sparse spectral approximations of complete graphs. We describe an emerging paradigm for the design of efficient algorithms for massive graphs. Constructing linear-sized spectral sparsification in almost-linear time, by Lee and Sun.

Spectral graph theory, which studies how the eigenvalues and eigenvectors of the graph Laplacian (and other related matrices) interact with the combinatorial structure of a graph, is a classical tool in both the theory and practice of algorithm design. Chung, F. Chapter 1 in "Eigenvalues and the Laplacian of a Graph." September 29, 2011 Spectral Theory for Planar Graphs 1 Introduction In 1996, Spielman and Teng proved a long-conjectured upper bound on the second eigenvalue of the unnormalized Laplacian for planar graphs: 2 = O(1=n). NSF CCF-0915487: \Spectral Graph Theory, Point Clouds, and Linear Equation Solvers\. Spectral sparsification I suggest you'll watch Spielman's talk Miracles of Algebraic Graph Theory to get a sense of what this course is mostly about. Random walks on graphs, expander graphs, clustering, and several other combinatorial aspects of graphs are intimately connected to their spectral properties. In this tutorial, we will try to provide some intuition as to why these eigenvectors and eigenvalues have combinatorial significance, and will sitn'ey some of their applications. We combine all classic sources, e.g. Title Authors Year Venue PR Cited By Graph sparsification by effective resistances. 15 Simple Spectral Bisection May Fail (Guattery & Miller) I’m here because he was my friend’s undergraduate advisor and my friend said that “Professor Dan” is great!

Core topics in Laplacian systems and spectral graph theory One of the major advances at the interface of spectral graph theory and numerical linear algebra is the development, starting with the seminal work of Spielman and Teng, of near-linear time solvers for diagonally dominant linear systems. Abstract. CS 229r Spectral Graph Theory in Computer Science, Lecture 1-1 Unlike in Spielman, our de nition accommodates self-loops, which are directed edges of the form (a;a). Spectral graph theory emerged in the 1950s and 1960s. Spectral Graph Theory or Algebraic Graph Theory, as it is also known, is the study of the relationship between the eigenvalues and eigenvectors of graphs and their combinatorial properties.
